摘要
Digital filter technology isan importantmethod in study of geomagnetic pul- sations in Antarctica.The signals received by pulsation magnetometer on the ground include varioustypesofmagnetic pulsations.Some types of pulsations or some frequen- cy bands of pulsations can be extracted from the signals by means of digital filter tech- nology because types of pulsations are defined according to their frequency range.In this paper usual digital filter technology is provided for study of magnetic pulsations in Antarctica and some examples are introduced.
